Subject[PATCH V9 07/11] PCI: Factor DT specific pci_bus_find_domain_nr() code out
Date
pci_bus_find_domain_nr() retrieves the host bridge domain number in a DT
specific way. Factor our pci_bus_find_domain_nr() in a separate DT
function (ie of_pci_bus_find_domain_nr()) so that DT code is self
contained, paving the way for retrieving domain number in
pci_bus_find_domain_nr() with additional firmware methods (ie ACPI).
